摘要:
The invention provides a heterogeneously loaded type of fast reactor core in which a reduced number of target fuel assemblies containing minor actinide nuclides are heterogeneously dispersed and loaded. A wrapper tube for each of the target fuel assemblies is of the same shape and size as a hexagonal wrapper tube for an ordinary core fuel assembly. Each of target fuel rods within the wrapper tube contains 20 to 50% of minor actinide nuclides, and has a diameter more reduced than that of an ordinary core fuel rod. The number of the ordinary core fuel rods loaded in the ordinary core fuel assembly is 271 while the number of the target fuel rods loaded in the target fuel assembly is 331 or 397. Thirty to 50 such target fuel assemblies are heterogeneously dispersed and loaded in the fast reactor core.
摘要:
Neptunium of minor actinide nuclides separated from spent fuel is added to fuel of reactor cores (inner reactor cores and/or outer reactor cores) of a fast reactor and americium of the separated minor actinide nuclides and rare earth elements are added to either or both of radial and axial blankets of the fast reactor for burning. Thus, the minor actinide nuclides with long half-lives can be burnt with the fast reactor core with the minimized effects of the rare earth elements. For a burner reactor, americium and rare earth elements may be added to shields for burning. Curium may be added together with americium and rare earth elements. Neptunium is added in amount of 2% to 5% by weight based on the weight of the fuel and the rare earth elements are added in an amount of 50% by weight or less based on the weight of the fuel. A Purex process is used to separate neptunium and a Truex process is used to separate americium and curium.
摘要:
Novel amide derivatives are disclosed. As examples of said amide derivatives are mentioned 1-[2-(5-(3-methoxy-4-benzyloxyphenyl)-2,4-pentadienoyl)aminoethyl]-4-diphenylmethoxypiperidine, 1-[2-(5-(3-methoxy-4-pentadienoyl)aminoethyl]-4-diphenylmethoxypiperidine and 1-[2-(5-(3-methoxy-4-ethoxymethoxyphenyl)-2,4-pentadienoyl)aminoethyl]-4-diphenylmethoxypiperidine.

摘要:
According to the invention, there are provided novel amide derivatives and 5-lipoxygenase inhibitors containing the same as an effective ingredient.The above-mentioned compounds of the invention have been demonstrated to posses 5-lipoxygenase-inhibiting activities. These compounds can inhibit the production of leucotrienes such as LTC.sub.4 and LTD.sub.4 which are allergy-inducing factors by inhibiting the activity of 5-lipoxygenase. Accordingly, the amide derivatives can be used as 5-lipoxygenase inhibitors effective for allergic asthma, allergic rhinitis and the like.
